An FBI forensics expert testified Wednesday that DNA from former Rep. Gary Condit (D-Calif.) was found on underwear that belonged to federal intern Chandra Levy.

Condit, with whom Levy was romantically linked, was once considered a key suspect in the case. But another man —Ingmar Guandique, a 29-year-old illegal immigrant from El Salvador — is now on trial in D.C. Superior Court for her death.
